What is the total resistance of this?

First, open a spreadsheet on Excel, following the example below:


- Then measure the resistance of the intersecting spikes only for the grey area.

- Write the measured value in the intersecting cell.

The sheet will give you the total resistance...

Golly thanks Tim but after a lifetime in electronics I don't even know what's a "plug with spikes"

It seems to me that you overlooked a lot of stuff in your "lifetime"..

A plug with 15 spikes is not the way I'd call it either but it's easily understood.

Maybe a 15-pin connector would be better..

Boy Tim have I ever

But aren't there a whole lot of resistors involved

I don't need to know what kind of components are behind the connector.

I just gave a method for doing a measure, whatever weird its purpose is..

Tim I'm just beginning to vaguely grasp: Evidently the connector terminals are somehow wired together and we're required to measure the R between one extreme and the other
